A light producing screen comprises a layer 8, Fig. 6, composed of electroluminescent phosphor material, an impedance layer 9 of material possessing a non-linear "current versus voltage" characteristic both layers being sandwiched between a system of first and second grid conductors 10, 11, the first grid conductors being on the impedance layer and extending transversely of the second grid conductors on the phosphor layer, and means such as the rotors 17, 18, Fig. 5, for sequentially applying signal voltage to all of said conductors. Preferably the grid conductors are connected to their respective biasing electrodes 12, 13 by decoupling resistors 14, 15. The sequential signals applied by the rotors 17, 18 correspond to the line and frame scanning of the normal television screen. The material selected for the impedance layer 9 may be a semiconductor, a polarister or a ferro-electric material and the biasing field is such as to maintain polarisation of the layer at near saturation. Under these conditions, only the signal voltage applied across the selected grid intersection effectively overcomes the impedance to excite the phosphor, the extraneous voltage pulse between selected and unselected strips being thereby ineffective with a resulting increase in contrast between the wanted signal and its background. Specification 751,047 is referred to. Reference has been directed by the Comptroller to Specification 746,502.

Abstract: 746,754. Casting-machines. COKE, C. Jan. 4, 1954 [Oct. 2, 1952], No. 24648/52. Class 83 (1). [Also in Groups XI and XII] A casting-machine comprises an electric furnace having a dome and a base which are provided with a corrugated-metal casing of high tensile strength and reinforcing wire of the same material wound in the corrugations, the casing preventing the escape of inert gas through the wall of refractory material bonded to the inside of the casing. The dome can be raised by a rack and pinion 2 to allow escape of air and inert gas as metal ingots in the runner-cup 25 of a mould 24 are melted, as by indirect-arc, highfrequency or other electric heating; the heating elements may be built ,into the mould and connected to the electric supply when the mould is placed in the furnace. When the casting- temperature of the metal has been reached, the dome is forced down, guided by members 17, to seal against a layer of compressible refractory material in a groove 18 in the top of the base. Hot inert gas is forced into the furnace through inlet 7 under the control of valves 8, 15, and thermostatic equipment controls the temperature of the metal, which is registered on a pyrometer. The casting in the baked and heated refractory mould, which may also be cased in metal, may be cooled rapidly by raising the dome, or slowly by stopping the supply of gas and electricity.
